How do hydraulic systems work?
A hydraulic systems works on the idea that, unlike gasses, liquids cannot be compressed. By using this idea you can set up a system that transfers pressure through liquid to aid in the lifting of an object. One great example of this at work is the breaks in your car.

How do pneumatic systems work?
pneumatic systems serve to amplify force applied. If you apply a force on a large piston transfered to a small piston it increases the force applied. this applies more to hydraulics because it has limited compressibility.

What are the major diffrences between hydraulic and pneumatic syatems?
Hydraulic systems uses liquid or fluids, and pneumatic systems uses gases or air.
